           Summary: Telepathy Contact List crashes when on switching from
                    online to offline mode
           Product: telepathy
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: contactlist
        AssignedTo: kde-telepathy at kde.org
        ReportedBy: wizard.karan at gmail.com


Application: telepathy-kde-contactlist (0.1)
KDE Platform Version: 4.6.80 (4.7 Beta1) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.38-8-generic-pae i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

I was going offline and online successively, and then suddenly when I went
offline, the contact list crashed.

I tried this again, and sometimes this happens and sometimes it doesn't, though
one thing is sure, it always happens when I switch to offline mode.

The crash can be reproduced some of the time.
